[dfdl-wg] Updated documents

[Robert E. McGrath]

Thanks Martin.

I think this is coming along very nicely.  The mists are clearing for
me, I'm beginning to understand how this is going to work. :-)

In particular, the Conversions docuement, section 6 (pp. 8-9) is
starting to make a lot of sense to me.

I'll be interested to hear what others think of this material.
